Can you please try new kernel 5.15.0-201.135.6 and see if it still has the problem. If it does, can you please

  1. upload /var/log/messages file after you did 'sudo modprobe iwlwifi'
  2. previous kernel that worked fine

Hi, The problem does not occur in the vmlinuz-5.15.0-201.135.6 kernel. Thank you!
